I have followed the data sheet of LM567 to build up a circuit to encode 10kHz input singal, but it doesn't work........ :cry:
I used R1=2k, C1=47nF, 0.1uF and 0.01uF at pin 1 and pin 2.
It seems no center frequency appeard, all input signals with different frequencies have the similar value of output voltage..........
What can I do??? Did I make any mistake???
Please help me.... :wink:
